The Heating Ventilation and Air Conditioning (HVAC) System in your building accounts for about half of the buildings energy use. That’s why choosing the right Heating Ventilation and Air Conditioning System or retrofitting your existing one represents a huge energy and cost saving opportunity. Capacity and efficiency are the two primary factors you need to consider when choosing an HVAC system. Heating Ventilation and Air Conditioning System design has improved dramatically in recent years. The development of new energy efficient design technologies has coincided with the increased precision in HVAC sizing. An experienced HVAC company and facilities management team can apply these new technologies to save you money on energy.

HVAC Sizing and HVAC Load Calculations

One of the first steps in proper HVAC sizing is to determine the cooling and heating load of your building. Cooling and heating load is a measurement of how much capacity you’ll need from an air conditioning or heating system to sufficiently control the temperature of your space. The capacity of air conditioning units ...
... for example is measured in BTUs per hour.

Proper HVAC sizing for your space is essential to the efficient operation of your system. Too large or too small a Heating Ventilation and Air Conditioning system will mean an increase in energy costs. Over-sizing is a common problem particularly in the cooling component of many existing Heating Ventilation and Air Conditioning systems. Often the original HVAC load calculations were made at a time when equipment like computers and lighting threw off a lot more heat than they do today.

The most common method for performing HVAC load calculations for both new and retrofit design analysis is to use the ACCA (Air Conditioning Contractors of America), Manual J-compliant load calculation software. HVAC sizing takes into account a number of factors about the building including:
